ROBERT'S'I'ANLEY BROWN, 0]? LONDON, ENGLAND.

Application filed. Kovember 1, 1921. Serial No. 512,153.

To all whom it may concern:

Be it known that I, ROBERT STANLEY BROWN, of London, England, a subject of the King of Great Britain and Ireland, have invented certain new and useful Iinprovements in and Relating to Closures for Bottles, Tins, Jars, Containers, and Receptacles, of which the following is a specification.

' Wherever I herein use or refer to any of the four words:lid, lids, lids, lids, I re: for to and include any and all herein (as well as now) mentioned or described caps, lids, capsules, covers and the like and any'o'f their kinds.

Wherever I herein use or refer to any of the four words :-recep tacle, receptacles, receptacles, receptacles, I refer to and include any and all herein (aswell as now) mentioned or described bottles, tins, jars, containers and receptacles and any of their kinds.

Wherever I herein use or refer to any of the four words :rim, rims, rims, rims, I refer to and include any and all herein (as well as now) mentioned or described rims,

dependent flanging, skirting, bands, or rimlike formations, and any of their kinds, whether integral or non-integral with a lid, used in any suitable lid retaining manner in one piece or suitably joined pieces, or interruptedly formed.

Wherever I herein use or refer to any of the four words Lock, locks, locks, looks, I refer to and include anyone (or any great- 36 er number) of any and all of the herein mentioned or described manners, forms, types, and classes of rim provisions and means whereby arim engages a receptacle (or its attachment or attachments) to ob- 40 tain a secure or positive shouldering hold thereon.

Wherever I herein use or refer to any of the four pairs of conjointly used words: Receptacles grip, receptacles grips, receptacles gr1ps, receptacles grips, I refer to and include any one (or greater number) of any and all of the herein described, or stated receptacles portions or revisions for e aging the said lock or ocks, All the ove definitions are intended to apply to the description of and all claims for, this invention, namely, a receptacle provided with at least one exterior engaging grip constructed to effect its engagement in a shouldering like manner at a substantially uniform engaging height with respect to the said rece tacles axis and a lids rim inwardly eformed (after application (to the said receptacle) at well'separated space intervals to form locks adapted to engagingly coact with the said receptacles gripping provision, such locks having elow the level of their engagement) side supporting connection with a non-locking portion of the said rim, said locks being so accessibly disposed with respect to said rece tacle as to admit of said rims removal wit out destruction of the non-locking portion of the rim, said rim being so constructed as to be suificiently pliable to readily re-distort outwards on inside pressure being applied to its locks.

In such manner I obtain a few points of locking hold, having only to outwardly redeform one or at most but a few locks to speedily remove even the largest closure, yet without the inherent lack of lock stability with respect to the rims body usually existing in inwardly bent engaging rims tongues, scallops, and the like. By'the formation of the looks at the time stated I not only avoid all necessity to use screwing methods of a plication and so avoid the risk of the distur ance of annular sealing media, but I am able to comply with the other numerous' special requirements incidental to preserving putrefactive goods and the rapid closing of'receptacles; as well as to conform to shapes .of receptacles grips most easily produced in "sheet metal, and pressed and automatically made vitreous material and the like. 7

I shall hereafter refer to a few genera forms of receptacles ips, a few general forms of inwardly de ormed locks, and a few manners of locally strengthening the latter or the rim or the lid in general, or

' locks) weakenin the same, most of which said forms an manners are clearly not novelbut on the contrary, obviousl forms an manners which packers are we 1 accustomed and equipped to efiiciently carry into effect with most numerous variations. Such lock and rim strengthening however when used is Obviously limited to an amount tp give strength without prejudice to the said pliability of the rim, otherwise the said intended rim freeing possibility would be frustrated. I am aware it has been proposed to emplo incised and other indents in rims s ecially stiffened to have no such said pha ility and on receptacles where the lock material was inaccessible to be re-deformed to its non-locking original state; as also to position locking lugs in lain portions of rim fianging the latter so stiffened and the lugs so inaccessibly positioned as to be unsultable for my said manner of removal and moreover arranged in special combinations with roughened turning flanging. To all such construction I ma re no claim herein, nor to any kind of lock fully formed prior to application to its receptac e or of a character essentially entailing such prior forma tion; shapes of deformed indents hitherto em loyed being obviously most numerous.

he said side supporting non-locking portion of the rim I prefer to form to have bearing (substantia ly in the line of the against the receptacles external periphery to prevent the rim being sprung off and to thus generally stabilize the rim and its looks. I

This invention relates to rims of innumerable sha ings, being for example applicable to inkwe ls, pepperettes, holed lids (with or without hinging), in fact to any pliable closure rim formation or flanging capable of use with a receptacle shaped externally in the immediate vicinity of its orifice in accordance with the requirements apparent from this description, whether such vicinity be oval, round, rectangular, or other geometrical or irregular shape.

The rim or lid may be made of iron, tinplate, brass, aluminium, electroplate, tagger sheet. or any other suitable material or materials.

Hereafter I use the following numbers as a reference to the features or conditions they indicate. This invention may be used for closures of 1) hermetic, (2) pressure resisting (3) hermetic vacuum (4:) automatic vacuum, types; each with (5) such regulatable automatically re-seating safety valve action as is desired; and by this inventions constructions and application method, excepting where I state otherwise, the foregoing five closures can (6) fulfil their holding duties without damage or permanent dis lacement of locks,

(7) have sealing (an re-sealing) comression applied and retained to any desired egree (8) be ire-applied in the original, or a new,,

receptacle damage when applying despite their usual inaccuracies,

(13) be readily and speedily removed without special appliance,

(14) resist-internal receptacle pressure to tihekactual shear or destruction strength of co s,

(15) be applied without turning the lid, thus preventing disturbance or injury of annular sealing media,

(16; resist transit disturbance,

17 retain or prevent loss-of sealing media when the lid is removed,

(18) have exceptionally liberal deformation of lock, with correspondingly increased hold and liability of obvious lock destruction in releasing,

(19) automatically tend to draw the locks inwards as the internal receptacle pressure rises,

(20) retain indefinitely cold pressures, and without structural alteration still release identical pressures under high internal temperatures,

(21) be made of less material than heretofore possible for these combined conditions,

(22) be applied rapidly with human power only and without having to rotationally register a lid to a receptacle,

(23) automatically adapt itself to the many processing methods used for foods, and whether wholly or partially cooked in the receptacle after closing,

(24) in one form of construction and application meet all requirements above, as well as selected combinations thereof, under which conditions the closure is generally characterized in that it is constructively proportioned as though the receptacles internal pressure was a load'and the lid or rim the load support, whose span (lock spacmfig strength, and stiffness have been scienti cally proportioned by static considerations and conditions to get a recoverable specific deflection of the lid or rim between the locks to obtain ressure release under such load with ac compensation for (and consideration of) the following factors (when present) :-the extent to which the sealing medium is compressed to allow for receptacle inaccuracies together with its initial and ultimate compression desired; temperatures expansion effects; processing time, temperature, and method; the recoverable yield, spr1ng, and strength properties of the lock. V

I use a receptacle which has 1n one or more suitable positions any indentationsor projections or shaping or provision which would obviously provide a receptacle grip for rim locks of the nature herein set forth, as, for example, grooving, fianging, beading, recessing, bosses, folds, seams, corrugations, false r full wiring, or combinations thereof, selected and shaped as suits the receptaoles construction or material.

i The locks which engage with the receptacles grips may be of any suitably disposed form of pushed in rim material the hereinstated deformation process could form, a few, for example, being dentures, indents, cuts, slots, pips, in fact any configurat on I choose to embody in the after stated incismg and deformation tools, excluding as state the few proprietary special combinations f locks hereinbefore mentioned.

I may use any suitable sealing medium, media, or packing, in ring, laminated, disc .or any other suitable form, shape, or cross section, whether loose, held by adhesion, or any other suitable means, rrespective of position, and whether placed, folded, crimped, seamed, or applied in plastic or fluid or solid condition into any suitable rooving or any other suitable position in (or on) the lid, rim, or the receptacle. For exam 1e I may use cork, fibre, paper, 'papler mache, balata, though for most purposes 1 use dependably impervious material, such as rubber, rubber compositions, impregnated cork (or paper) and dispose sealing media between the lid or rim and the receptacle.

An example of application of the closure is as follows :--I first apply (mechanically as a freely. fitting or by hand) the lid or rim to the receptacle member, unprovided as yet with fully formed locks (though sometimes with partially formed looks or auxiliary engagements), said sealing medla being in the sealing position. I next place the receptacle on a floatably (or cushioned) supported table. directly beneath a fixed tool holding head provided with receptacle centering guides. By a spring governed foot lover, orany other suitable means, the table is raised, the receptacle centering 1tself in the said guides and its lid or rim being brought up to meet the tool head truly flush, as receptacle inaccuracies are compensated for by said floating table, latter table being preferably leather faced.

erably mechanically constrained plungers attached to the said head now give to the rims exterior surface, usually in a normal direction thereto, a blow or blows in such position that the rims material at any suit,- able position is forced intosome form of shouldering engagement with one or more of the receptacles grips, thus forming locks. Said plungers may be blunt, or excising, or both, and so shaped at their tips so as to form and inwardly deform rim metal as to make locks of the af orestated yp I over compress the sealing medium beyond what I finally require, so that the rim metal where forced inwards to form locks amply clears inaccurately positioned or formed receptacles grips. This obviates damage to receptacles, and on the said table ,being lowered, by using resilient sealing media, the latter forces the lid or rim to rise, the locks then bearing on the said grips. A bevelled underside of a receptacles grip, if struck by a plunger, obviates receptacle breakage as the resultant vertical reaction 'on the said underside only adds (by slight sidiary ones (or stated equivalent applianccs) which make the locks.

By spacing the locks apart proportionate to a rims strength, or desirable amount of yield, (with due regard to temperature expansion efi'ects in-processing when necessary) or keeping the locks few-in number, or by suitable combinations of these features, I easily obtain in'one closure above numbered features :12, 13, 14, 18, 22, as well as 3, 4, 5. 6, 20, 23. the latter six features resulting, by the ability of the lid or rim to materially (and recoverably) yield between the locks, to further assist which yield I may locally strengthen (or as well as) weaken the lid. or rim. or rims edge, (or all 'of these) by any suitable means. excluding as aforestated means of a proprietary character. For example localized weakening may result by my employing one or more suitably disposed cuts, slots,

scallops. holes. or by strengthening where. yield 's not desired by one or more internal" or ex erpal bulges, internal and external projections, indentations, seams, folds, all which strengthening formations (or combinations of same) I may use as part of the lock itself for stren hening same and some forms assist the forming of locks, and

suitably disposed other forms will obviously fulfil condition 17.

"I may apply locks before or after processing, .or both before and after to recompress the seal, or to take up permanent set in same, by means of a rlms new on position.

The receptacle may be one having rips, or series of grips, disposed at varying evels (interrupted, continuous, or roughened, as desired) or also have suitably disposed protuberanccs to meet and force out the looks when the applied rim is turned. For condition 8 or this new on position I may use a receptacle, or rim, or both, having respectively receptacles grips or looks disposed at varying levels, or auxiliary engagements (optionally similarly disposed) of any well known suitable type, for example :-snap-in, or snap-on, bosses o r indents, pips, hooks, tongues, and the like, these suiting condition 10.

Receptacles or rims or" lids may have in any suitable position or positions-one or more:rccesscs, indentations, projections, or any other suitable configurations serving as rim removing fulcra, additional rim or lid registers. retainers of sealing medla, preventors of lateral rim play, guards against rim disturbance, and any other suitable provision of equivalent purpose.

The rim may be removed by forcing out the locks with a prong, or by any other suitable means for forcing the same outwards, or the lock provided with a wire or tongue to pull it outwards, said Wire. or any other suitable means may retain lids or rims to receptacles to avoid their loss.

In closures (or even in the same closure) for condition 5, I may use locks unequally spaced and formed, some designed to permanently yield, others to recoverably yield, and for condition 9 somewhat brittle rim metal may be used. I prefer cut looks (or slot locks) deformed respectively in towards or on to, suitable receptacles grip, as obtain a metal shearing hold, which hold (properly spaced) suits all closure conditions I have numbered 01' set forth herein.

The lid and rim and receptacle are of any kind which is of a suitable shape or type to conform to the requirements and said characterization of the invention, which requirements are readily understood from the description and drawings here provided, it being obvious that many unstated innumerable combinations of my herein stated constructive features can be efi'ectedwithout departing from the spirit of this invention.'

I may, for example, suitably dispose and use my stated strengthening formations in innumerable ways and directions to give/a general (or localized) strengthening to a rim, or lids top.

This invention permits of shallow rims, using little material, as a receptacles beading if very shallow provides a suitable grip, as it is subjected to less stresses than is customary for a closure of my properties. I thereby save rim material, and receptacle cost. The invention may be used eithen to retain a stopper or non-hermetic closure.

Referring to the drawings filed herewith Fig. 1 is a perspective view of a receptacle showing one form of closure made in accordance with this invention partly in sectlon;

Fig. 2 is a perspective view of another form of closure;

Fig. 3 is an elevation of a circular closure;

Fig. 4 is a perspective view of a closure as applied to a rim band;

Fig. 5 is a perspective view of closure and receptacle embodying this invention.

In each of all of the attached figures, I show one of the many forms of closures in accordance with this invention. In these figures a is the receptacle, 6 the lid, 0 the rim, 0? strengthening formations for the} rim or the lock, 6 the receptacles top, 7 the I'oceptacles grips, g auxiliary receptacle grips, permitting of varying on positions for the rim or lid, h packing on the receptacle, j strengthening formations on the lid, k k locks for engaging f or g on the receptacle, Z a protuberance on the receptacle to co-act with the locks, forcing the latter out of locking position, when the lid 7) is turned, m m weakening (or strengthening) formations which affect the rims or lids yielding tendency to facilitate or regulate safety valve action.

In all drawings, the locks are presumed to have been proportioned or spaced commensurate with the pressure of sealing, rim strength, and extent of lid or rim yield for condition 5.

In the perspective (partly sectioned) view shown in Fig. (1) is exemplified a form relating to all claims. The ample distance between A1 and k permits of pro-determined yield of the lid in somewhat arched form between 11 and 0 when internal receptacle pressure reaches that which the closure is designed to release, Such release would occur past the sealing medium h (in this case a ring of rectangular sectioned rubber) and between the positions 7? and q, and 0 and n. The position of the strengthening dishings m, and the weakening formations m all help this effect, and locks formed on the correspondingqrim sectors of m are particularly immune from disturbance. d in this case is an all round internal fold but uninterrupted at the scallop m, m. 1' tends to retain it. 1' is an indent, numbers of which may be placed on the rim (at several levels) to serve as light grips for preliminary (or re-) application of the lid (1n a new. or more'than one looked on .posi

. tion if desired) and any disposed between the weakening s ots m are usually preferred, rim metal here being more yielding. Along the line 0 s is a ridge caused by defective moulding. The upper face of the deformin tool t, should it encounter the track of this ridge on the receptacles grip (in this case the all round bead f) may cause a breakage of the receptacle, were it not'for the factthat it permits the receptacle to probably avoid this at the expense of a little extra compression of hat the position 0, possible in virtue of the liberal lock spacing. I show this closure applied by means such as described herein, u being the floating table top, which on rising presents the top of b flush to the toolhead w, intended to abutt (or register) on Us top (and carry a plunger for deforming theu'im, t). The locks k and k are engagingly formed after applying 6 'to e. This closure exemplifies all the numbered twenty four features.

Fig. 2shows perspectively a form of the invention illustrating how proper selection and comblnation of themeans herein described readlly gives a closure innumerable properties I have stated. The outline is made with one press operation in one piece, the rim having a series of buttresses (six being shown). It is presented to a compound cutter, which at one operation makes three parallel rows of cuts w, y and z. The :1? row serves to weaken the rim to yield better as alight safety valve. The 3 and 2 rows enable a suitable plunger (or rotary tool) to later force inwards any. rim metal below (or between) them to serve as locks duly strengthened by the corrugations w, the rim therefore having two op- 'tional locking positions on a suitably disposed receptacles grip. The bent in portions 1) may provide suitable register with this grip to prevent side play of the rim. The buttresses act as anti-disturbance cushions during rough handling of the closure.- This type exemplifies all the numbered twenty-four features except 17, 19, 24 and 7, and allows of easy a justment of'lock spacing (its sealing medium being placed on the top, or top and side of a receptacle).

, This type may obviously work in conjunction with a like receptacle as shown in Fig. 5. 1

Fig. 3 shows in elevation a circular cover of like utility as in Fig. 2 and adapted to work on a like receptacle. The locks comprise tongues such as n or 0 (or both) dethis flanging. I is a fold. ,This type ex- M emplifies all the twenty-four numbered featuresexcept 14-, 17, 19 and 24. Tongues such as 9, may be used to pull out the locks. Fig. 4 shows perspectively the invention in the form of a detachable tongue jointed rim having flanging p to retain in place any suitable receptacles cover; its crescent lock having like sealing compression properties as the lock of Fig. 3, in addition to its lock being to some extent recoverably yielding. This'tygie exemplifies all the numbered twenty our features, exce t 9, 17 24, and 18 partially.' The formation J makes the look less liable to tear. g is an indent (vertical) for registering the rim with a suitable tool heads pip, so that plunger tools (if desired) need not strike the rim where it is joined. It may obviously work in con- 'u nct{on with a like receptacle asshown in Fig. 5 shows perspectively an extremely simple and effective form. It is seated on e, the latter optionally having V-shapfed or any other suitable ooves. d is an all round internal fold sometimes crimped or V formed with varying depth and strength and also optionally omitted or interruped between the locks for better safety valve action of the lid). The lock here shown is almost touching the throat o for register. The ridge it serves as a fulcrum for a prong to prise the locks outwards when desired.

The rim may be slotted in any suitable form as at. yso that one or more plungers may act directly on any suitable u turned (internal as well as external) rim e ge formations (for example d) to deform and open out the upturned form only to be the lock; this type being very strong and va-. riable, specially suiting recoverably springy locks for features 4 and 5, or non-sprin locks, and also household preserving wit out special appliances. This type exemplifies all the numbered twenty-four features excepting feature 7 which may be got by suitable readjustment of the lock forming tools, and feature 17 by adding suitably disposed plunger indents to the rim. In Fig. 1 at k and k and in Fig. 5 at y'the inner tends to substantially either become less flat (that is to say, it opens out inwardly) or to remain unaltered in distance with respect to the outer opposite flanging on formupturned fold d at these locking situations ing the lock, due partially to the acuteness and flatness of the fold and the fact that this look metal is not buckled against the receptacles throat byv the deforming tool." In Fig. 3 the locks will comprise inbent shaded portions such as r the fold d being well below the actual line of locking engagement. In Fig. 1 at-la as at Fig. 5 at y the incision in the rim wall makes no engagement.

In all figures whether the locks are the edges of incisions or not it will be noted that in each case where lock strengthening has been resorted to, rovision has been simultaneously made for the ready distortion of the rim back to that non-locking contour which it had prior to the lock formation, by maintaining the pliability of the rim, and for arranging for the initial deforming act (and its material weakening consequences) to occur at the place where rim strengthening is present yet without materially impairing t e strengthening of the rim in respect of resisting vertical strains.

What I claim and desire to secure by Letters Patent is l. A closure combination comprising a receptacle provided with at least one exterior engaging grip constructed to efi'ect its engagement in a shouldering like manner at a substantially uniform engaging height with respect to the said receptacles axis and a lids rim inwardly deformed (after application to the said receptacle) at well separated space intervals to form locks adapted to engagingly coact with the said receptacles gripping provision, such locks having (below the level of their engagement) side supporting connection with a non-locking portion of the said rim, said locks bein so accessibly disposed with respect to sai receptacle as to admit of said rims removal without destruction of the non-locking portion of the rim said rim being so constructed as to be sufficiently pliable to readily re-distort outwards on inside pressure being epplied to its locks.
